Yoshimura - RS-4 Signature Series Full System (Husqvarna)
Development takes time and the Yoshimura's Husky FC450 application now has the answer for real power when it comes to exhaust. These kind of gains in power and torque don't come overnight, but are developed in testing, in the dyno room and on the race track. Available as a full system in either stainless/aluminum or titanium/titanium, the Yoshimura RS-4 Signature series full system for Husqvarna will not dissapoint.
